Not now-a-days Chris,
I run a day-cab tractor, so I stay in a hotel 3-4 nights outta'da week.
So I use one in a gas station convenience store or at the hotel.
Back when I ran long haul, I had the room to install and run power converters for fridge, microwave, TV and such.
Man! Either way, Convenience store, or Hotel, I bet there are some heads turning when the wonderful smell of that Home Cookin blows out the vent of the microwave.
I know I'd be lookin and a sniffin. Yum!
